Baer Circular Die HSS is a precision external-threading tool designed for general metalworking. Ideal for machinists, repair technicians, and DIY enthusiasts, it delivers clean, accurate left-hand threads on cylindrical stock with ease.

• Material: High-Speed Steel (HSS) construction for wear resistance and long tool life.
• Thread Type: Left-hand UNF threading, 7/16" diameter with 20 threads per inch (7/16 x 20 UNF, left-hand).
• Size / Pitch: 7/16" diameter, 20 TPI, optimized for reliable left-hand thread formation.
• Cutting Edges: Precision-ground cutting edges designed to produce clean, consistent threads with minimal burrs.
• Compatibility: Designed to be used with standard die stocks or die holders for stable rotation and controlled cutting.
• Applications: Perfect for external threading on cylindrical stock in general-purpose machining, maintenance, and fabrication tasks.
• Durability: Hardened HSS construction provides longevity under repeated use and cutting fluid exposure.

Using this Baer die, you can efficiently create or repair left-hand external threads, ensuring a snug fit with corresponding fasteners or mating parts. The combination of HSS hardness, precise edge geometry, and compatibility with common die stocks offers reliable performance across automotive, machinery, and workshop projects. For best results, apply suitable cutting fluid, maintain proper alignment in the die stock, and rotate with steady pressure to maximize tool life and thread quality.
